The Model 100 Iodine-Stabilized He-Ne laser is a primary length standard
based on the 1997 CIPM Mise en Pratique. It differs from other
commercially available lasers, (e.g., polarization- or Zeeman-stabilized
lasers) in that it requires no calibration in order to realize its full
accuracy. It is designed for ease of use, with automatic peak identification
and acquisition allowing unattended operation and use by "non-specialists."
Its rugged and compact design makes it suitable for laboratory and field
applications in precision measurement, laser spectroscopy, and standards
work. All operating specifications are guaranteed, and have been independently
confirmed in many intercomparisons with the BIPM, NIST, and other national
standards labs.
